ALIS: Autonomous Learning in Intelligent System


Intelligent systems are machines that have their own goals, perceive, respond and learn based on their experiences. Reinforcement Learning (RL) is a powerful tool for this purpose because the system autonomously learns a policy, through trial and error in repeated interactions with the environment. This project seeks to increase the dissemination of the RL technology and advance the frontiers of knowledge of the self-learning area. However, many challenges must still be overcome in order to have a broad use of RL in intelligent systems. Challenges include dealing with uncertainties of sensors and actuators, a dynamic world that changes continuously and requires quick decisions, continuous quantities and the high RL computational cost. Therefore, this scientific research project aims toinvestigate, propose, develop, and evaluate models and methods to make efficient and effective RL in intelligent systems that solve complex problems. In particular, it explores: (I) relational and object-oriented models and algorithms, opening opportunities for generalization in the representation and solution of complex problems; (Ii) distribution and division of workload among several apprentices agents; (Iii) appropriate approximation functions to represent both situations observed by the agent and the knowledge acquired; (Iv) knowledge transfer so that the knowledge acquired byanother agent or after the learning of previous tasks can be reused to accelerate the learning of a new similar task. From the point of view of applications, this project aims to implement and evaluate models and algorithms in areas such as games, robotics, computational biology, among others. (AU)
